doi:10.16183/j.cnki.jsjtu.2021.S2.005

Abstract

Abstract:

This paper proposes an intelligent stability quota management technology based on structured rule strategy library, designs a set of automatic identification of section rules and adaptive adjustment methods of quota based on structured rule library, and constructs a section dynamic monitoring and power grid rule library with East China characteristics. Embedded in the D5000 system, it provides reliable structured process management, automatic identification of stability limit, adaptive adjustment of stability limit, and visual monitoring and analysis of out of limit section in an intuitive and concise form through unified display means, which provides a strong technical support for dispatching.

Key words: intelligent stability limit, structuration, rule policy library, automatic recognition
